</span><span lang="EN-US" style="font-size:10.0pt;font-family:"Arial",sans-serif"><br>

Regarding a virtual meeting, we have conducted some internal work on a "Distributed CFDP Concept" to cover the needs of our upcoming Earth Observation missions with very high downlink rates. While we currently believe that this concept does not (necessarily)

 require changes to the CFDP standard itself, it might be interesting to present the concept to the working group.</span><span lang="EN-US" style="font-size:12.0pt">

<br>

</span><span lang="EN-US" style="font-size:10.0pt;font-family:"Arial",sans-serif"><br>

Actually, we aim at standardising  a Return CFDP PDU Cross-Support Service to support this concept. This would be under the responsibility of the CSTS WG where Holger Dreihahn already presented the concept during the last meeting. Nevertheless, it is of course

 important, to define this service in close collaboration with the CFDP WG (if there is interest).</span><span lang="EN-US" style="font-size:12.0pt">

 Charter have been completed, I don</span>’<span lang="EN-US">t plan to schedule a virtual meeting of the WG next month; the only question on the table, I think, is whether to terminate the WG at this point or instead to place it in a

</span>“<span lang="EN-US">dormant</span>”<span lang="EN-US"> (hibernation) state, much like the Voice WG.<o:p></o:p></span></p>

<p style="margin:0cm;margin-bottom:.0001pt"><span lang="EN-US">The SIS WG chairs agree that the latter is preferable: more work on CFDP will become necessary at some point in the future, and the administrative procedures for starting up a new working group

 are time-consuming.  Resuming the operations of a dormant WG to address new issues is vastly easier.<o:p></o:p></span></p>
